A genuine OEM sliding waste cover for Thetford cassette toilets. Designed to cover and protect the opening of the waste holding tank compartment in C2, C200, C3, and C4 series toilets. Helps prevent odours, leaks, and keeps the interior clean when in use or during transit.

For proper operation and hygiene, the waste tank compartment should have a cover that seals effectively. This sliding cover is made to match the original part, fitting cleanly into the cassette slot so the tank can still slide in and out as needed.
